Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a grant delay request to a base station. The grant delay request may indicate a future time, at or thereafter a base station is requested to allocate resources to the UE. The base station may transmit the uplink grant to the UE allocating the resources to the UE based on the grant delay request, and the UE may transmit, to the base station, an uplink transmission including the uplink data based on the uplink grant. The UE may transmit the grant delay request as part of a scheduling request (SR), or as part of a buffer status report (BSR), or a combination of these.
Legal claims defining the scope of protection, as filed with the USPTO.
5. The method of claim 3, wherein the future time is a defined number of slots after a slot in which the scheduling request is transmitted.
8. The method of claim 7, wherein the future time is a defined number of slots after a slot in which the buffer status report is transmitted.
10. The method of claim 1 wherein the future time is indicated using a reference time.
12. The method of claim 1, wherein the first scheduling request signature is selected before the uplink data is available for transmission.
15. The method of claim 1, wherein each of the plurality of scheduling request signatures is a different bit sequence of a plurality of bit sequences.
18. The method of claim 17, wherein the uplink grant indicates a grant of resources corresponding to the future time indicated in the grant delay request.
20. The method of claim 17, wherein the future time is indicated using a reference time.
